Enum RevisionState 

pub enum RevisionState {
    Present {
        value: Vec<u8>,
        revision: Revision,
    },
    Missing {
        revision: Revision,
    },
}

The committed state of one logical document key.

Missing is intentionally not represented as Option: a deleted key retains the LSN of its deletion so optimistic validation can detect ABA.
